According to fellow comedian Marlon Wayans, it may not have been depression that led to Robin Williams' tragic suicide Monday, but rather, the antidepressants he may have been taking.

"I think there's something in these medicines that people are taking for depression that's making them depressed and making them commit suicide," Wayans candidly said in an interview with Fusion Live. "I swear, I don't think it's depression. I think it's chemical. There's some kind of antidepressant drug that they're taking that's causing them to have visions and making them kill themselves. There's drugs out there -- if you take it, and if you're of certain descent -- it will make you a little crazy. I just feel like, it's chemical."

"I don't think it's just him going, 'Hey, I'm going to slit my wrist and choke myself,'" he added. "I mean, I just think there's something else that's in there. ... I mean, he was such a joyful dude."

According to Williams' rep, the actor had been battling "severe depression as of late." He was found on August 11, 2014 in his bedroom with a belt around his neck, with cuts on the inside of his left wrist, by his personal assistant.

In the new interview, Wayans, 42, went on to express his admiration for the legendary actor.
